The original steel folding bike built for the city. Proudly handmade in London since 1975. It transforms from a go-anywhere vehicle to a small, locked package in under 20 seconds.
You can go anywhere with your C Line. Weighing about the same as a small suitcase, it's easy to lift, carry and store. Going further? Fold halfway, to tow, roll or glide.

Welcome on rush-hour trains. Tucks in car boots or under restaurant tables. You don’t lock and leave a Brompton, it travels with you. So, every day just works.

4 or 12-speed. For flatter cities, short rides and even infrequent use, less and simpler is often better, and lighter. But other times, you might want – or need – more. |
